Fix Bug 840: DefaultEDTUtil.restart() shall only reuse ThreadGroup (tg) is not destroyed, otherwise use current thread's tg.
With jdk7u40, when re-launching a NEWT applet (JOGLNewtApplet1Run), i.e. via browser back and forth, the following exception happens: java.lang.RuntimeException: java.lang.IllegalThreadStateException at com.jogamp.newt.awt.applet.JOGLNewtApplet1Run.init(JOGLNewtApplet1Run.java:218) at com.sun.deploy.uitoolkit.impl.awt.AWTAppletAdapter.init(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.IllegalThreadStateException at java.lang.ThreadGroup.addUnstarted(Unknown Source) at java.lang.Thread.init(Unknown Source) at java.lang.Thread.<init>(Unknown Source) at jogamp.newt.DefaultEDTUtil$NEDT.<init>(DefaultEDTUtil.java:280) at jogamp.newt.DefaultEDTUtil.restart(DefaultEDTUtil.java:91) at jogamp.newt.DisplayImpl.runOnEDTIfAvail(DisplayImpl.java:231) at jogamp.newt.WindowImpl.runOnEDTIfAvail(WindowImpl.java:1758) at jogamp.newt.WindowImpl.setUndecorated(WindowImpl.java:1477) at com.jogamp.newt.opengl.GLWindow.setUndecorated(GLWindow.java:278) at com.jogamp.newt.awt.applet.JOGLNewtApplet1Run.init(JOGLNewtApplet1Run.java:188) ... 3 more This is due to 7u40's changed ThreadGroup (tg) lifecycle, i.e. the tg is destroyed. In such case, DefaultEDTUtil.restart() shall use the current threads tg.
